She possesses a dignified atmosphere that leads others to think she is very mature, which she actually is. She takes care of the others, while living in the school, being remarkably calm in difficult situations.

Later in the manga, Kurumi encounters Megumi who was unconsciously guarding the shelter room in their school and was attacked while in shock of the recent event. Fortunately the group finds an antidote at the same place and cured her in time. It is unknown to what extent the antidote cured her as she is noted to have "cold hands."
